Found the recipe. My grandmother always used her hands to mix this, something about the heat in your hands. Anyway, I hope you like it if you make it.....
½ lb (2 sticks) butter, softened
½ c. confectioner’s sugar, sifted (if you live in Canada and can get Fruit Sugar, use that)
2 ¼ cups AP flour, sifted.
Mix everything together with your hands. Roll out into a big oval on a cookie sheet, about ½ inch thick. Using a fork, poke holes all over.
Bake 275* on a low rack of the oven about 1 hour or until golden brown. Sprinkle with granulated sugar on top and slice while still warm
